Patch Review

Same pattern as patch 3, applied to `GspSequencer`, `GspSeqIter`, and `GspS=
equencerParams`. All three are already lifetime-parameterized with `'a`, so=
 this is a mechanical replacement.

In `boot.rs`:
```rust
-            dev: pdev.as_ref().into(),
+            dev,
```

This is correct =E2=80=94 `dev` was already the right `&'a` reference from =
the function parameter (confirmed by reading boot.rs:220-224 in the tree, w=
here `pdev` is a `&'a pci::Device` and `pdev.as_ref()` yields `&'a device::=
Device`). Wait =E2=80=94 looking more carefully, the existing code has `dev=
: pdev.as_ref().into()` which converts via `ARef::from()`. The new code jus=
t uses `dev`, but the field in `GspSequencerParams` is changing from `ARef<=
device::Device>` to `&'a device::Device`. The `dev` variable in `boot.rs` c=
ontext would need to be `pdev.as_ref()` or equivalent. Let me check what `d=
ev` refers to in the patched boot.rs.

The diff only shows line 707 changing `dev: pdev.as_ref().into()` to `dev,`=
. Since `GspSequencerParams::dev` is now `&'a device::Device`, and the surr=
ounding context has `pdev: &'a pci::Device<device::Bound>`, the field initi=
alizer `dev` must mean there's a local variable `dev` of type `&'a device::=
Device`. Looking at the existing boot.rs, `pdev.as_ref()` returns `&device:=
:Device<device::Bound>`. But `GspSequencerParams::dev` is `&'a device::Devi=
ce` (no type parameter). This works if there's a `Deref` or `AsRef` coercio=
n from `Device<Bound>` to `Device`. But the shorthand `dev,` means there mu=
st be a local variable named `dev` already in scope. Without seeing the ful=
l function, this likely refers to a variable computed earlier. This appears=
 fine given the existing code structure.

In `sequencer.rs`, the `.clone()` on ARef is replaced with a simple copy of=
 the reference:

```rust
-            dev: self.dev.clone(),
+            dev: self.dev,
```

And the `&self.dev` dereference becomes direct:

```rust
-        let cmd_result =3D GspSeqCmd::new(&buffer, &self.dev);
+        let cmd_result =3D GspSeqCmd::new(&buffer, self.dev);
```

Both correct =E2=80=94 `&'a device::Device` is `Copy` (it's a reference). T=
he `sync::aref::ARef` import is properly removed.

No issues found.
